METHOD OF VIBBA'I'ING OBJECTS.

Original application filed September 12, 1921, Serial No. 500,193. Divided and this application illed April 18, 1924. Serial No. 707,398.

To all whom it may concern:

Be it known that we, JOHN T. STONEY, a resident of Lakewood, and KLEMENS PUR- WIN, a resident of Cleveland, bothin county Cuyahoga, and State of Ohio, both citizens of the United States,-have jointly invented a new and useful Method of Vibrating Objects, of which the following is a specification.

The subject matter of the present application was originally disclosed and resented in our application for method an appara ms for shaking out foundry flasks and the like, filed September 12, 1921, Serial No. 500,193, and was divided out of that application on April 11, 1924.

Our invention relates to methods of oreating vibrations in objects.

The main object of our invention is a simple, inexpensive, and effective method of vibrating objects for such purposes as loos-' ening adherent matter from objects, or ejecting matter from an object, for instance.

the apparatus shown in the accompanying drawing and the operation thereof.

Our invention is illustrated in the accompanying drawing whichshows certain mechanism or apparatus engaging'a certain foundry flask and adapted to vibrate the same, for the purpose of carrying out our method. It is understood, however, that apparatus other than that shown can be employed to vibrate theflask shown, that the apparatus flasklshow'n', and that apparatus other than th'atshown can be employed to vibrate obother than the flask shown, within-the scope of the appended claims. Irrespective of the ap aratus employed, or

I the object to be vibrate the present invention contemplates that the object is suspended in some manner, preferably so that the major body portion thereof is free to vibrate in all directions. Such expediencies as merely laying the object on a table or other simi- 'lar support and slowly jarring this table or support,'as in a molding machine for instance, is not included in thepresent invention and is not contemplated therein, but it is *"oontemplated to so dispose the object in relation to the suspension mechanism, that the object can respond freely to sharp and re. id

have adhered to the inside of the walls thereof due to previous casting operations.

This flask A is provided with the usual trunnions 10 which form a convenient means for suspending the-flask in this instance.

The suspension means shown comprises a crane hook having two .legs B, each leg mainly of chain formation in the present instance, joined at the top by the ring 11, and provided with the hook 12 at the bottom to en age the respective trunnion.

n the present instance, the legs B are siaced apart by the adjustable s acer bars so that those portions of the egs which contain the vibrators D are di substantially vertical to favor the particular type of vibrators shown.

The vibrators D are connected or incor porated in the legs B and are secured to the chain portions thereof by the bolts 13 passing through the plates 14 and the ears 15 of the present vibrator.

Each of the vibrators shown is of the .PIQS. sure air type well known in the art, each having the previously mentioned ears 15.

Pressure air, or other similar pressure fluid, operating in an apparatus similar to an air hammer, are convenient and effective ,means for carr ing out the present method cars 15 and from there into the legs and into the'hooks 12. Since the hooks contact the trunnions 10, these vibrations are transmitted from the hooks into the trunnions and into the main body of the flask.

Since the flask is so suspended that the major portion thereof is free to vibrate in all directions, the vibrations set up in the trunnions cause this body to vibrate sufficiently severe to loosen matter adherin on the flask or to remove or eject matter cm the flask.

In order to get best results in a method as above described, the main or major portion of the body of the object should be free to vibrate in all directions as previously stated. The trunnions on the flask shown provide a convenient means for suspendin the flaskto. permit such free vibration. t is not necessary, however, that the object should be suspended from a plurality of points on the outside thereof although such means of suspension gives very good results. A single suspension of the object, from the center of gravity for instance, will answer the urpose as long as the major portion of the body is'free to vibrate.

We are aware that modifications can be made in the method and meansof suspen sion shown as well as in the method and means for creating vibrations shown, therefore, without limiting ourselves to the precise method and apparatus set forth,

We claim 1.. The method of vibrating objects, com- .prising, suspending an object to be vibrated,

2. The method of vibrating objects, cornprising, suspending an object to be vibrated so that the main body portion thereof is free to vibrate in all directions, and creating vibrations in the means on which said object is suspended.

3. The method of vibrating objects, comprising, suspending an object to be vibrated by a plurality of outer points thereof, and creatin vibrations in the means on which said ob ect is suspended.

4. The method of vibrating a foundry flask, comprising, suspending said flask by the trunnions thereof, and creating vibrations in the means on which said flask is suspended. a

5. The method of vibrating objects, comprising, suspending an object to be vibrated, and creatin vibrations in the means on which said 0 ject is suspended by a pressure fluid vibrator.

6. The method of vibrating objects, comprising, suspending an object to be vibrated, and creating sharp and rapid vibrations in the means on which said object is suspended.-

7. The method of vibrating objects, comprising, suspending an object to be vibrated, and creating vibrations in the means on which said object is suspended by an air pressure vibrator.
